Bacterial amidases are essential to split the shared envelope of adjunct daughter cells to
allow cell separation. Their activity needs to be precisely controlled to prevent cell lysis. In …

Cytokinesis in gram-negative bacteria requires the constriction of all three cell envelope
layers: the inner membrane (IM), the peptidoglycan (PG) cell wall and the outer membrane …

In Proteobacteria, integral outer membrane proteins (OMPs) are crucial for the maintenance
of the envelope permeability barrier to some antibiotics and detergents. In Enterobacteria …

Summary rpoS is the structural gene for σs, which is a second vegetative sigma subunit of
RNA polymerase in Escherichia coli and is involved in the expression of many stationary …

The outer membrane (OM) is the defining feature of gram-negative bacteria and is an
essential organelle. Accordingly, OM assembly pathways and their essential protein …

Outer membrane lipoproteins of Escherichia coli are released from the inner membrane
upon the formation of a complex with a periplasmic chaperone, LolA, followed by …

The Gram-negative outer-membrane envelops the bacterium and functions as a
permeability barrier against antibiotics, detergents, and environmental stresses. Some …

Escherichia coli has five genes encoding l, d-transpeptidases (Ldt) with varied functions.
Three of these enzymes (YbiS, ErfK, YcfS) have been shown to cross-link Braun's lipoprotein …

The outer membrane (OM) of Gram-negative bacteria is a selective permeability barrier that
allows uptake of nutrients while simultaneously protecting the cell from harmful compounds …

In Gram-negative bacteria, a dedicated machinery consisting of LolABCDE components
targets lipoproteins to the outer membrane. We used a previously identified small-molecule …
